Michele,

I’m not arguing tired light theory, just pointing out that the speed of light is being treated as the denominator, as in the metric in which this expansion is denominated in. It is “redshift.” That means the light is taking longer to cross the space. So if space is not the determinant of the speed of light, what is?

Is there some underlaying dimension/vacuum, other than the expanding universe, determining the speed of light????

I assume you have heard of the inchworm on an expanding balloon analogy, for light crossing this expanding space. So what determines the speed of the worm? It has a set speed, that is different from the expanding balloon. These are two metrics of distance/space. The balloon is expanding under the worm, as well as everywhere else, so it is a different metric and they are being related to one another!

It doesn’t matter whether it is Constant, or not. It is still the metric against which this expansion is measured. The redshift, remember? It is redshifted, because the light takes longer to cross this expanding distance.

If the speed of light were Constant to this expanding ruler, it would have to increase proportionally, so that it would still measure Constant to the ruler.

But then it wouldn’t REDSHIFT!!!!

I just don’t know how to explain this any clearer, so pardon me, if I seem frustrated. Doesn’t anyone understand the concept of fractions? The expansion is relative to the speed of light. THAT is why it redshifts!!!!!

That makes the speed the denominator, while the expansion is the numerator.

The light takes LONGER to cross. There are more lightyears!!!

What is the basis of the speed of intergalactic light, the vacuum through which it crosses at C, if it’s not intergalactic space?

Of course, one reason the Big Bang Theory works, is that whenever it doesn’t, some enormous force of nature is proposed and all is well. What if accountants could just write in a figure and call it “dark money,” whenever they find a gap in the books? It would certainly make their work a lot easier. That’s how cosmology seems to work.
